First, download the EAGLE Program, which allows you to design plates with their components and make paths.

Redraw the echo hello-world board

I created a new document schematic

I applied the option “Add part”
Then, download the FABACADEMY website to find the necessary components on the board.
And, I was extracting from the repository every necessary component, and added a led plus a button, and resistance.

Then, begin to link each component with the ATTINY according to the digital terminal.

I put name “PB3”

You can see the electronic design
I added a resistor, led, and a button

I applied the option “Generate/switch to board”

Before entering the DRC option, I installed and enabled the fab library, I put the option “Use all”

After I went to the Design rules (DRC) option, I loaded the fabcity-designrules library.

In the clearence option was placed 16 mill, by the reference of the size of wood milling cutter that will be used.

To burn the bootloader, I need to identify the port in wich the FTDI cable was pluged,

then in the tool tab, begin to set the information, board, processor, port.

Then I did the programming, which consists of the LED light turning on every time I press the button, also
For that I looked for the table of equivalences between the ATtiny and the Arduino,so I can choose the right pins.
